Frank: Take a deep breath....one of the experts will be along shortly to give you an understandable explanation of your scan results. The only thing that I will say is that my personal research on the topic of PET scans leads me to believe that they are NOT always to be believed!
Don't freak...it doesn't help....obviously, further tests are warranted. Try to concentrate of the positive results which appear to confirm the absence of oral cancer.
Keep us posted as to your progress, and know that we're all thinking of you during this trying time!
